Question

multiple select question select all that apply select all of the following that explain why the fossil record is incomplete. fossils were not formed south of the wallace line due to proximity to the equator. fossils older than 100 million years old have already decayed past the point of recognition. many organisms decomposed before they were buried in sediments. erosion and movements of the earths surface have destroyed many fossils that did form. many fossils may never be discovered because they are buried deeply or submerged under water.

Explanation:

Fossils can decompose before burial, be destroyed by erosion and Earth - surface movements, or remain undiscovered if deeply buried. These are valid reasons for an incomplete fossil record. Fossils not forming south of the Wallace Line is not related to the incompleteness of the overall fossil record.

Answer:

C. Many organisms decomposed before they were buried in sediments.
D. Erosion and movements of the Earth's surface have destroyed many fossils that did form.
E. Many fossils may never be discovered because they are buried deeply or submerged under water.
